Title: Improvements in liquid fuel burners
IPC: F23N5/02
Filed: 1926-10-04
Abstract: 269,404. Marks, E. C. R., (Williams Oil- O-Matic Heating Corporation). Oct. 4, 1926. Electrically controlling fuel and air supplies.- A thermal coil 8 containing an expansible fluid operating the control switch in the main circuit of an electric motor driving the fan and pump supplying air and fuel to a burner nozzle 5 is subjected to the full heat of the flame when the burner is first ignited and later, when the switch has been operated, cool air is passed through the housing 10 containing the coil so as to shield the coil from the full heat of the flame. In the construction shown a plate valve 11 pivoted over a port in the air conduit 1 is raised by the expansion of a bimetallic coil 14 in the housing 10 so as to divert some of the air from the conduit 1 through the housing. The valve 11 may be centrally pivoted and arranged to draw some of the combustion gases from the fire pot through the housing into the conduit 1 when the burner is first ignited. When the thermal coil 8 operates the main switch through a Bourdon tube, the Bourdon tube may operate the valve 11 through a wire connection. The valve 11 may alternatively be arranged to close the port in the conduit 1 when the burner is first ignited and open a closure pivoted in the bottom of the housing to allow the combustion gases to escape through the housing to the chimney stack or fan intake. After the coil 8 has become heated the valve 11 opens the port in the conduit 1 and closes the closure in the bottom of the housing. In another modification, the valve 11 is omitted and only the pivoted closure in the bottom of the housing is operated to admit atmospheric air to the housing, as the temperature in the housing increases.

Title: Transmission systems
IPC: H04B17/40
Filed: 1972-05-25
Abstract: 1381554 Supervizing unattended repeaters STANDARD TELEPHONES & CABLES Ltd 25 May 1972 24690/72 Heading H4R A dependent repeater in a line transmission system provides a locally generated pilot signal when a failure of the transmitted pilot signal is detected. The system includes both regulated and unregulated repeaters and the latter are arranged to switch to a predetermined gain on detecting a failure of the pilot signal which could result in the received signals being outside the working range of the terminal station amplifier. To restore some control at least one dependent repeater with a circuit for monitoring the presence of the pilot signal and an oscillator for locally generating a pilot signal when necessary and a time discriminating arrangement for preventing the locally generated signal affecting the monitoring circuit. As shown, the local oscillator 21 can provide the pilot signal when enabled by output m 1  of multivibrator M. The pilot signal on the line is monitored by the circuit comprising filter F, amplifier A a rectifier R and when it is outside the operating range for a time longer than delay D (5-10 seconds) the multivibrator M is enabled. The multivibrator provides a signal at m 1  for 1. second and a signal at m 2  for 10 milliseconds so that the oscillator 21 operates for 1 sec. and following a delay of 2 msec. imposed by delay d the amplifier A is enabled for 8 msecs. and monitors the line for restoration of the transmitted pilot signal when the multivibrator is disabled. In typical line transmission systems different delay periods may be used depending on the location of the repeater. Additionally loopback can be provided to operate with further oscillators to give a fault location facility.

IPC: H05B37/02
Filed: 1932-09-07
Abstract: 407,073. Control of A.C. and D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.- (Assignees of Livingston, O. W.; 841, Main Avenue, Schenectady, New York, U.S.A.) Sept. 7, 1932, No. 24969. Convention date, Sept. 11, 1931. [Class 38 (iii).] The varying effect of a saturable inductance 15, controlling a load circuit 11, when the load is varied is corrected by changing the voltage condition of the grid of a valve 16 in the saturating circuit so that, for example, the illumination of lamps 10 in a theatre will correspond with the setting of a control element 17 whatever the lamp load may be. The grid circuit contains a resistance 34 across which a constant potential difference is maintained and a resistance 39 across which is an opposed and pulsating potential derived from the load circuit so that it varies with the voltage on the circuit. A second valve 42 may be employed when the valve 16 is a half wave rectifier to maintain the current in the saturating circuit throughout the A.C. cycle. According to the Specification as open to inspection under Sect. 91 the device was stated to be applicable to the field circuit of a motor or of a Ward Leonard generator. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to pushbutton devices
Inventor: JEWITT MICHAEL
IPC: H03K17/968
Filed: 1962-06-29
Abstract: 996, 761. Photo-electric control devices. EXPRESS LIFT CO. Ltd. May 22, 1963 [June 29, 1962], No.25101/62. Heading G1A. [Also in Division H3] A device comprises a light source 2 Fig. 1, a photo-electric sensor 1, a shutter 7 movable between positions in which it shields and does not shield the sensor from the light source, a pushbutton 4 mechanically connected to the shutter, and a translucent shield 6, the light source being operable at two intensities of illumination the higher of which is effective to illuminate the pushbutton through the translucent shield. In the embodiment sensor 1 is a photo-transistor and two filament lamps 2 constitute the light source. In the circuit arrangement, Fig. 2, the collector of the photo-transistor is connected to a NOR unit 13 the output from which is connected to a NOR unit 15, having a second input 17; thus units 13 and 15 connected as shown afford a memory circuit which is reset by a signal 17. Output 18 is fed to a NOR unit 21 the output from which controls lamps 2. NOR unit 21 Fig. 3 includes a transistor 25 the base of which is connected to inputs 20 Fig. 2; its output circuit is connected in parallel with a resistor 26. When transistor 25 is non-conducting i.e. in the present convention when there is a '1' output from NOR unit 21, lamps 2 glow at low intensity sufficient to excite photo-transistor 1 but, because of shield 6 Fig. 1, insufficient to illuminate push button 4; when transistor 25 is conducting, lamps 2 glow sufficiently to be seen from in front of the push button. In operation, assuming that the latest event is a reset i.e. '1', input to NOR unit 15 there is a 'O' output from the latter and thus lamps 2 glow at low intensity and phototransistor 1 produces a "O" output. If the push button is now pressed momentarily, there is a "1" output from the photo-transistor and the lamps 2 glow at high intensity. The push button may be utilized as a landing call button in a lift service, the higher illumination indicating to the caller that the call has been registered; when the call is answered a reset signal is applied at input 17.
